Johnson, Park Forest, 111., assignors to Structural Clay Products Research Foundation, Chicago, 111., atrade association Application October 11, 1954, Serial No. 461,366 4 Claims. (CI. 33-85) This invention relates to an aligning device to be used by masons to facilitate and accelerate the laying of brick and similar building materials and more particularly it relates to masons guideline carrying corner pole and accessories therefor to support and maintain the corner pole in an operative position.

Masons aligning devices, that is, bricklayers devices to insure uniformity of courses in a brick wall and devices to promote accuracy and uniformity in laying up the brick and mortar in a brick wall, are not new. Many different forms of devices to increase the work output and accuracy of a mason, as well as to make it possible for unskilled workmen to accurately erect a wall of brick which is plumb and uniform, have been on the market and known for a number of years.

Most of the devices, however, are unduly complicated and unwieldy to operate. The corner pole of many of the aligning devices usually requires very accurate plumbing, measuring and adjusting in order to place them in an operative positive. Other similar devices require different types of corner poles for different types of Walls or for different locations of the wall. devices cannot be used or accommodated to different types of masonry walls, foundation conditions and scaffolding arrangements without substantial modification or interference with job scheduling and masons work movements.

Our aligning device, comprising a new and novel form of corner pole and equipment used in connection therewith, eliminates the above disadvantages while retaining and adding to the advantages known in such devices today. In this respect, our corner pole is comprised'essentially of three elongated members and is of U shape. This type of construction permits the use of two guide lineholders in the same plane thereon, each guide lineholder having four separate surface areas by which the guide lineholder may be slideably secured to the corner pole. The corner pole is also provided with a movable marked scale to indicate course heights. We have also provided equipment useable with such corner pole to secure the corner pole to different types of masonry walls and foundation conditions.

A general object of our invention therefore is to provide an accurate bricklayers aligning devices comprising a corner pole and accessories therefor to facilitate and accelerate the laying of bricks and the like.

Another object of the invention is the provision of a corner pole and em ipment to be used in connection therewith which will accommodate the general types of masonry walls, foundation conditions and scaffolding arrangements.

Another object of this invention is to provide a corner pole generally of U-shaped construction which will receive two guide lineholders in the same plane and present four separate bearing surfaces so that the lineholders may be moved independently of each other.

Still another object of this invention is to provide an improved corner pole having a moveable marked scale Still other States Patent 2,931,104 Patented Apr. 5, 1960 to readily indicate difi'erent course heights of the brick units being laid.

Still another object of this invention is to provide a corner pole having improved means used in connection therewith to support the corner pole at salient and reentrant corners.

Yet another object of this invention is the provision of a corner pole having an improved top connector to attach an inside corner pole to an outside corner pole or to provide attaching means whenever scaffolding must be set up on the same side of the wall as the corner pole.

Yet another object of this invention is to provide means for securing an intermediate pole to a long, uninterruped wall to carry guide lineholders thereby providing independent guide lines.

Yet another object of our invention is the provision of an aligning device which is simple in construction and operation and relatively inexpensive to manufacture.

These, and other objects and advantages of this invention will hereinafter appear and for purposes of i1- lustration, but not of limitation, preferred embodiments of this invention are shown in the accompanying drawings in which:

Referring now to the drawings in detail, the letter C generally designates the corner pole contemplated as part of the subject invention and the letter L designates the guide lineholder which is best adapted for use with the corner pole C. The guide lineholder L is the subject matter of United States Patent :2;7 15,777, owned in common by the assignee. It is of course to be understood that the design andconstruction of the guide lineholder may be vention preferably is comprised of two two-by-fours (2" x 4") poles, a and 10b, and a two-by-two (2" x 2") rod 12 which is secured between the two poles 10a and 10b and at one end thereof by any convenient means such as by wood screws. The poles 10a and 10b and the rod 12 should be straight and long enough to be about eight inches (8") taller than the wall desired to be' built. Of course, the sizes of the poles 10a and 10b and the rod 12 may be varied without departing from the scope of this invention. Similarly, a variety of materials may be used to accomplish the desired results, but we have found that wood is more manageable, inexpensive and available than other materials.

A coursing scale 14 comprised of a strip of wood approximately one inch by one-and-three-quarters inches (1 x 1%") and having a plurality of indices 16 on the face thereof is adapted to be secured to either side of the rod 12 as is desired and explained more fully hereinafter. The indices 16 may simply be pencil marks or saw cuts. The coursing scale 14 may be secured to the rod 12 by form nails 18 or other similar means. The distance between the indices 16 on the coursing scale is the spacing of the vertical coursing of the brick work. v The coursing scale 14 may be secured to the rod 12 before or after the corner pole C is erected and plumbed. In the event that the coursing scale 14 is placed on the rod 12 before the corner pole is erected, the indices 16 are placed on the coursing scale 14 after the corner pole has been erected, plumbed and the level of each corner pole at each corner determined. This is to insure a common correct starting point for the bricks to be laid. In the event that the coursing scale is placed on the corner pole after it has been erected and plumbed, the indices 16 have already been marked and the coursing scale secured at the appropriate place to insure common level between the corner poles.

It has been found that it is most convenient to secure the coursing scale 14 to that side of rod 12 where the masons are working. That is, if the masons are working around the exterior of the wall, the coursing scale 14 should be secured to the outer side of the rod 12 and vice versa.

Substantially identical V-shaped plates 20 consisting each of a base portion 22 and a pair of arms 24 are secured to the top of the corner pole C as by bolts 26. Each of the arms are provided with openings 28 to receive bolts 30 and the like passing through braces 32 to give stability to the corner pole when the corner pole is erected as described hereinafter. The braces 32 can be made of scrap tWo-by-fours (2" x 4") and are to be long enough to anchor the corner pole to the ground or foundation.

Whenever it is desired to place the braces 32 away from the corner pole or whenever it is desired to use two corner poles at a corner such as in the construction of a cavity type wall, etc., a connector 34 is provided. The connector 34 is generally of an elongated U shape and comprises a base portion 36 and a pair of arms 38 which are flared outward as at 40 adjacent the end thereof in much the same manner as the arms 24 of the plates 20. The connector 34 may also be provided with a flange 42 adjacent and between the end of the arms 38 to give rigidity to the connector 34.

The corner pole C is provided with openings 44 which receive bolts 46 and the like which pass through the base 136 of the connector 34 to secure the connector to the top of the corner pole C. One of the connector arms 38 threadedly receives turn screws 48a and 48b which are usually several inches apart. The two turn screws 48a and 48b are all that are required to secure the connector 34 to another corner pole by means of tightening the appropriate turn screws against the corner pole C. This function is best illustrated in Figs. 4 to 6 of the drawings. Fig. 4 shows the position of the corner pole for an eight inch (8") wall and turn screw 48a is tightened to rigidly retain the corner pole between the arms 38 and the connector 34. Fig. 5 shows the position of the corner pole for a nine-and-one-half inch (9%") or cavity type wall and either turn screw 48a or 481) or both is tightened to retain the corner pole between the arms 38 of the connector 34. Fig. 6 shows the position of the corner pole for a twelve inch (12") wall, and the turn screw 48b is employed to rigidly retain the corner pole between the arms 38 of the connector 34.

If it is desired to use the connector 34 with braces, flared out brackets 50 of the arms 38 are provided with openings 52 to .receive bolts 54 and the like passing through the arms and braces 56 to rigidly secure the braces to the connector 34. The purpose of such a mounting will be pointed out hereinafter.

The corner pole C, depending upon the nature of the construction site, is usually mounted upon a foundation in the manner to be described. As the corner pole is mounted at a salient corner; that is, a corner wherein the walls run in a direction away from the corner pole as shown in Figs. 1 and 7, a salient corner base plate 58, substantially similar to that as shown in Fig. 7, is employed. The plate 58 is substantially of 'U-shaped construction and comprises a base portion 6%), substantailly parallel arms 62 which terminate in flared out support sections 64. Each support section 64 is provided with a lip 66 at its uppermost part for thepurpose of resting upon the top of a foundation wall 68.

The salient corner base plate 58 is secured to the bottom of the corner pole C as by bolts 70 and the like. The salient corner base plate 58 also has a J bolt 72 passing therethrough and the bottom of the corner pole.

The J bolt 72 secures a tie wire 74 which may be secured at its other end to an anchor plate 76 or any other anchoring means. The J bolt is tfastened and tightened by means of a ratchet handle 78. I

In mounting a corner pole Cto a salient corner, the salient corner base plate 58 is secured to the corner pole as described. The corner pole and the base plate 58 are then placed upon the salient corner as substantially shown in Fig. 7 of the drawings so that the lip 66 of the flared out section 64 of the arms 62 rests on top of the foundation 68. The anchor grip 76 is placed on the foundation as substantially shown in Fig. 7 and the J bolt is then tightened through the ratchet handle 78 to hold the pole temporarily until the braces 32 attached to the V-shaped plates 22 are set and secured to the ground, floor or foundation. Of course, if the corner poleis to rest upon a foundation such as shown in Fig. l, the tie wire 74 can be secured to a nail 80 set in the foundation or by some other convenient means.

If a corner pole C is to be mounted to a re-entrant corner; that is, a corner having the walls running in a direction towards the corner pole such as shown in Figs. 8 and 10 of the drawings, a difierent type of base mounting must be employed.

For a re-entrant corner, we have provided a re-entrant corner base plate 82 which is best illustrated in Fig. 8. This base plate is an angle iron 84 substantially of V- shaped construction which is wrapped around three sides of the corner pole C. The angle iron may be made of one piece or of three separate pieces as desired. Each of the arms 86 of the angle iron 84 has a channel bar 88 secured thereto as by welding, brazing or any other means Well known in the art. The channel bar internally and slideably receives a second channel bar 90. One end of the channel bar 90 is cut away so that the upper portion forms a lip 92. The channel bar 88 has an opening 94 which threadedly receives a turn screw 96. The purpose of the turn screw 96 is to freeze the movement of .the channel iron 90 within the channel bar 88 when the channel iron is appropriately set upon the re-entrant corner foundation.

The angle iron 84 is secured to the bottom of the corner pole as by bolts 93 or any other suitable means. The angle iron 84 also receives a J bolt 100 having one end of a tie wire 102 secured therein. ilhe J bolt is tightened by a turn screw 104 or any other similar means to draw the tie wire taut after it has been secured to any anchoring means such as a nail 106 or the like.

The corner pole at a re-entrant corner is mounted to the foundation 108 by merely placing the lips 92 of the angle iron 90 upon the edge of the foundation and temporarily securing the corner pole in an upright position by tightening the tie wire 102 through the J bolt 100 until the appropriate braces are secured to the top of the corner pole.

The foregoing description has dealt with the placing of corner poles upon the exterior side of a foundation of a wall to be built. In the event that it is desired to place the corner pole on the interior side of a wall, we have provided a different form of mounting base 110 which is designed to be used upon the slab of the foundation 112 as shown in Fig. 1 or or a wooden floor 114 as shown in Fig. 10. The floor mounting base 110 is generally of rectangular shape and preferably made of a metal. A plurality of openings 116 may be provided therein to receive nails 118 or the like to secure the floor mounting base to the slab 112 of the floor 114. If this method is not desired for securing the base to the slab or floor, bricks or other heavy material (not shown) may be placed upon the floor mounting base 110 to give the necessary rigidity thereto to maintain the corner poles in an erected position until the appropriate braces are set and secured. The floor mounting base 112 is secured to the corner pole by means of bolts 120 or the like which passes through an angle iron 122 secured as by welding or brazing to one corner of the floor mounting base 110.

In the event that two corner poles are to be employed at one corner, such as shown in Figs. 1 and 10, where a cavity or wall, twelve inch (12") or the like, is to be built, the combination of the mountings described above may be used. Two corner poles may also be used where both sides of a wall are to be laid to the guide line, as where both sides of the masonry wall are exposed.

Fig. 1 shows the use of a salient base plate 58 for the outside corner pole and a floor mounting base 110 for the inside corner pole. Fig. shows a re-entrant corner base plate 82 employed upon the outside corner pole and a floor mounting base 110 for the inside corner pole.

Where two corner poles are employed, the connector 34 is used to rigidly secure the two poles in a spacedapart relation as previously described. If the workmen are to erect the wall from the outside, braces 56 are secured to the fiared out brackets 50 of the arms 38 of the connector 34. The braces 56 in turn being secured to the flooring as by nailing or by piling bricks and the like thereon to give it the necessary rigidity. If the wall is to be built from the inside, the braces would be secured to the arms 24 of the V-shaped brace plates 22.

Even where only one corner pole is to be employed, the connector 34 may be used to place the braces on the inside of the building if the corner pole is to be mounted to the outside of the wall. Similarly, if the single pole is to be mounted on the inside of the wall, the connector 34 is used to carry the braces to the outside of the wall. Manifestly, the braces are set and secured to the ground or foundation opposite the side of the wall where the workmen will be working from in erecting the wall. This is to eliminate obstacles in the path of the workmen and also to permit the erection of scafiolding without interference from braces 32 or braces 56.

Where a long, uninterrupted wall is to be erected, we have found that the guide lines 124 tend to sag no matter how taut they are originally placed upon the lineholders L. In such a case, we have provided an intermediate mounting plate 126 such as shown in Fig. 11 of the drawings. The intermediate mounting plate 126 is essentially I-shape. The base 128 of the U-shaped plate The arms 130 slidably receive channel bars 132 having lips 134 formed at one end. The intermediate mounting plate 126 is secured to the bottom of the corner pole as by bolts 136 and is also provided with a J bolt 138 and turn screw 140 to tighten the J bolt in substantially-the same manner as that shown for the salient corner plate 58 and the re-entrant corner plate 82 and therefore a detailed description thereof will not be given here.

The intermediate pole which is the same construction as the previously described corner pole, is mounted on the wall by merely placing the lips 134 of the channel bars 132 upon the foundation 142 and the thumb screws 144 running through the arms of the intermediate plate 126 freeze the positioning of the slidable channel bar 132 thereon. This temporarily secures the pole until appropriate braces at the top of the pole are secured as described heretofore.

Fig. 13 shows the positioning of the lineholders L upon the intermediate pole and it particularly shows how continuity of the guide line 124, which would otherwise be present except for the intermediate pole, is broken by the lineholders L mounted thereon. Thus, the use of the pole intermediately disposed upon a long, uninterrupted wall prevents sagging of the guide line which would obviate the purpose of the guide line.

After the appropriate corner poles are erected at the various corners of the wall and possibly intermediate long walls, the guide lineholders L are placed upon the corner poles as described in the pending application thereon. As bricks are laid upon the foundation and as the wall is being erected, the guide lineholders holding the guide lines are moved upward, one indice 16 at a tim as is known in the art.

It is obvious that we have shown a new type of corner pole and accessories therefor to facilitate the laying of brick and similar building materials which is easy to assemble and inexpensive to manufacture. We have found after some familiarity with the subject matter of this invention, that walls may be erected at a substantially greater rate of speed without sacrificing any of the Workmanship in the wall with our corner pole and accessories therefor.

Although the particular embodiments of the present invention have been shown and described in some detail here, there is no intention to thereby limit the invention to the details of such embodiments. On the contrary, the intention is to cover all modifications, alternative embodiments, usages or equivalents of the improved corner pole and accessories therefor to facilitate laying of brick and similar building materials as fall within the spirit and scope of the invention as expressed and defined in the specification and the appended claims.
